Description

  [0001] The present invention relates generally to shoes and systems for securing a shoe to a foot. More particularly, the present invention relates to a system for securing a shoe to a foot using one or two pull-fit adjustment straps with fixed and floating buckles and loops.

  [0002] Various systems and methods are traditionally implemented to secure different types of shoes to a wearer's foot. Many such systems require the use of two hands to fully secure the shoe to the foot and to adjust the tightness of the fixed shoe to an appropriate level. However, many people, if not impossible, have difficulty in securing their shoes to their feet with both hands, because both hands do not reach them when wearing them. I understand that. In some cases, it may be possible to raise one foot in a shoe and then raise the other foot and place each foot on the opposite knee, thereby presenting the inside of the shoe. However, even in these situations, it is very difficult to fix a shoe and adjust its fit, even with traditional fastening methods such as shoelaces, or Velcro® type closures. .

  [0003] In the past, several attempts have been made using hook and loop structures (surface fastener structures) (such as Velcro® types) instead of shoelace systems. These are typically sufficient and cannot be properly adjusted for fit because they are limited to simple ones at the top of the clamp. It would be desirable to be able to adjust the fit of the shoe during the process, as well as one or more systems that can properly and adequately secure the shoe to the foot. Such a system requires access from only one side of the shoe, preferably only from the inside, and even users who have difficulty in reaching their feet can secure the shoe to their feet It is desirable to be able to adjust to.

  [0004] The present invention provides many embodiments in a general system for securing a shoe to a foot utilizing a series of single pull fit adjustment straps. Various embodiments each utilize a number of straps, some fixed and some variable in length, placed over and around the top and sides of the shoe at various locations. To do. At least one strap of the system provides an adjustable length (ie it can be shortened) so that all straps are pulled together so that they are horizontal and vertical across one or more directions, preferably across the sides of the shoe. It is possible to form a fit that tights the shoe in both directions. The present invention utilizes a variety of durable and lightweight nylon buckles, strips, anchor loops, and combinations thereof to allow attachment and movement of the adjustment straps across the top and sides of the shoe. A three-point mounting embodiment and a two-point mounting embodiment are included, each comprising a single pull adjustment structure. Many embodiments are built on the inside of the shoe, but in some embodiments are implemented on the outside of the shoe.
